Overview
341843 (2008 EV5) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2008 EV5 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2008 EV5 orbits the sun every 343 days (0.94 years), coming as close as 0.88 AU and reaching as far as 1.04 AU from the sun. 2008 EV5 is about 0.4 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, comparable in size to the U.S. Capitol building.
The rotation of 2008 EV5 has been observed. It completes a rotation on its axis every 3.73 hours.
Close Approaches
2008 EV5's orbit is 0.01 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.
2008 EV5 has 27 close approaches predicted in the coming decades:

Images and Observations
2008 EV5's orbit is determined by observations dating back to March 4, 2008. It was last officially observed on Nov. 17, 2022. The IAU Minor Planet Center records 1,017 observations used to determine its orbit.
Accessibility and Exploration
2008 EV5 can be reached with a journey of 362 days. This trajectory would require a delta-v of 6.291 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 320,844 potential trajectories and launch windows to this asteroid.
